The yoke 17 is held in position on the shaker lever 18 by means of the yoke arms 13. A handle nut 19 and bolt 20 are provided to permit the yoke 17 to be removed from the lever 18. Jlhe arms 13 slidably project between the projecting lugs 16 and pins or projections 15 formed on the sides ot the yoke 17. The breast roll shaker lever 18 is provided with a split bearing 21 at its lower end which is clamped onto a shaker shaft 22 positioned longitudinally along the rear side of the z nachine.v

Secured to the floor in rear of the shaker shaft 22 are a plurality of spaced pedestals or supports 23 each haying secured to the top thereof a wooden strip or spring 24. An upright wooden strip or spring 25 is also se cured to each pedestal 23. The springs. 24: and 25 are removably secured to the split bearings 26 of a plurality of shaker arms or levers 27 which are secured on the shaker shaft 22 and support the same in position with the aid of the springs 24 and 25. The springs 24 and 25 on the pedestal nearest the flow box end are removably secured to" the lever bearings 21. The mounting for the shaker shaft 22 is claimed in my copending application, Serial Number 5,696, filed January 30 1925, which in so far as its subject matter is disclosed herein is a division of the present application.

Movably engaged on each of the shaker levers 27 is a yoke 28. Bolts 29 and handle nutsBO are provided to permit the yokes 28 to be removed irom'the levers 27. pins or projections 31 are formed on the sides of each yoke28. Engaged on the shaker shaft 22 is a lever or arm 32 the outer end of which is connected to a link 33 is ecccutrically connected to a disk 3% rotated by a shaft 35. The shaft is operated by means oii gears 36 driven by a motor .37. Secured at intervals upon each base beam 1 are upright supports or pedestals So on the tops of which are secured extension arms chine are provided with openings 10 (Figure Decklc bars 41 are supported upon the tops of the arms 39 on each side of the machine and support the deckl-e rails 12. Deckle straps 43 are trained around decklc pulleys 1 1 and are supported intervals by suitable wheels or pulleys 45 Also mounted upon each pedestal 38 to the inside of the arm .89 are uprightwooden springs 46. Bolted to the tops of the springs "Wooden shaker strips or springs 52.

Guide The link The arms on the rear side of the ma-' messes 46 are the table roll rails 47. Mounted on the rails ll are a plurality of table roll bearings 18 each of which is provided with an adjusting mechanism 1-9. Table rolls 50 are supported in the bearings 48 beneath the deckle straps 43. T he Fourdrinier wire has been omitted for the sake of clcarness.

The operation is follows:

It will be noted that a Fourdrinier. section of a paper making machine has been illustrated and described in which the ordinary expensive and cumbersome supporting frame for the breast roll and. table rails is omitted and replaced by spring supports.

thereby. affording a: substantially frameles type of Fourdriniersection.

The shaker mechanisms are operated from the motor 37 which rotates the meshing gears 36 the shaft 35 and the disk Rotation ofthe disk at actuates the eccentric link 33 thereby causing the lever 32 to swing upwardly and downward ly to reciprocate the shaker shaft 22. The

shaker arms 18 and 2? arethereby rocked t'ti Ward and away from the the table rails and by meansof the members 52 cause shaking of the table rails 47 and the table rolls supported thereon. T he shaker arm 18 actuates the members 1 1 thereby causing a shaking motion to be imparted to the breast roll and the Fonrdrmier wn'e. The upright wooden spring members 9 and the spring men'ib-crs 6.

bers -16 support the table rails and permil the same to be shaken by the shaker apparatus hercmbefore described.

The deckle mechanisms are supported frame 1 lighter weight and less expensive construction is provided in which the wooden supporting spring members take the plate of the ordinary heavy metal frames and in which. the breast roll, the table rolls and the deride supports are adapted to be readily removed thereby permitting the Fourdrinier wire to be rapid y replaced when necessary. The spring supporting members are so arranged that access may be readily had to all parts of the Fourdrinier section which was not possible in the old heavy frame type of lfoui-drinier constructions. v

The base members may be adjusted by means of the screw-jacks 54 about the pivot members 2 to give the necessary pitch to the wire of the Fonrdrinier section.

While'the supports 6, 9, 24, 25, 46 and 58 are described as wooden members it will of course be understood that they may be made of any other desired materials.
